Question 118

Which particle-count description matches a monatomic ion with a one-minus charge?

  1. Equal numbers of protons and electrons
  2. One more neutron than protons
  3. One fewer electron than protons
  4. One more electron than protonsBonne réponse

Explication

A one-minus charge results when the ion has one more electron than protons, leaving one extra unit of negative charge. One fewer electron would reverse the sign and make the ion positive.
